At the risk of spoiling all this teenage enthusiasm with a few dull facts; Yes you can make sodium- obviously someone can because the stuff's on sale.The conceptually simplest way to make it from soda is to heat it with carbon- this was one of the first ways it was made. Of course, it's more than just mixing them up and borrowing your mum's oven.http://en.wikipedia.org/wiki/Sodium_bicarbonatehttp://en.wikipedia.org/wiki/Sodium

well sodium can be just made by heating the compound sodium chloride till its boiling point(800c)and by performing electrolysis by using cathode and anode of graphiteNOTE:sodium reacts easily with oxygen to form sodium oxide (Na2O),while chlorine can be very harmful to the lungs []
